How to glue the rearview mirror glass back on?

Shadowless adhesive, colorless, won't be noticeable after gluing, but must be applied on a sunny day as it requires UV light to dry; otherwise, it won't dry even after a day. Commonly available on the market is also specialized AB adhesive for rearview mirrors. This adhesive consists of two components, A and B, which must be mixed before use.

I always enjoy tinkering with car issues myself. Last time the rearview mirror glass fell off, and I glued it back. Don't rush to apply glue—first check why it fell off. It might have been due to high-pressure washing or aging causing looseness. Use a clean cloth to thoroughly clean the back of the mirror and the mounting base, removing any grease. Epoxy glue is the best choice, especially automotive-grade adhesive, as it bonds firmly and withstands temperature changes. Apply a small, even amount to the mirror base—avoid excess to prevent overflow. Align it carefully and press gently, using tape to hold it temporarily. Wait 24 hours for it to fully dry before driving, or bumps might dislodge it again. This method saves money, costing less than 50 yuan, but if you're unsure about the angle, it's worth visiting a repair shop. Be gentle when washing your car to extend the mirror's lifespan.

I suggest everyone think carefully about safety before attaching the rearview mirror. If it's not securely attached, it may affect visibility behind you, which is very dangerous while driving. If the glass falls off, carefully pick up the fragments first to avoid cutting your hands, and clean the surface with alcohol. Using double-sided adhesive strips for temporary fixing is acceptable, but for long-term use, specialized adhesives like silicone are necessary. From my own experience, after attaching, check if the angle is correct—if it's crooked, the mirror view will be blurry. It's best to buy a new mirror lens and install it to avoid potential hazards. Remember not to operate on rainy days, as humidity affects adhesion. This involves driving safety, so spending a little money to have a professional handle it securely is more worry-free and effortless.

A fallen rearview mirror is no small matter. Without it, changing lanes can easily lead to accidents. I’ve personally seen a friend get into a crash because of this. Quickly fix it temporarily with double-sided tape, but make sure to secure it properly as soon as possible. Use automotive-specific adhesive, apply it evenly, and press firmly for a few minutes to ensure it doesn’t tilt. Before sticking, clean the surface thoroughly to remove any dirt, or it won’t hold well. After repair, regularly check the mirror’s stability by giving it a gentle twist, and develop good habits to prevent it from falling again. Safety first—don’t delay.
